aa-exec
AA-EXEC(8) AppArmor AA-EXEC(8)
NAME
aa-exec - confine a program with the specified AppArmor profile
SYNOPSIS
aa-exec [options] [--] [<command> ...]
DESCRIPTION
aa-exec is used to launch a program confined by the specified profile and or namespace. If both a profile and namespace are specified
command will be confined by profile in the new policy namespace. If only a namespace is specified, the profile name of the current
confinement will be used. If neither a profile or namespace is specified command will be run using standard profile attachment (ie. as if
run without the aa-exec command).
If the arguments are to be pasted to the <command> being invoked by aa-exec then -- should be used to separate aa-exec arguments from the
command.
aa-exec -p profile1 -- ls -l
OPTIONS aa-exec accepts the following arguments:
-p PROFILE, --profile=PROFILE
confine <command> with PROFILE. If the PROFILE is not specified use the current profile name (likely unconfined).
-n NAMESPACE, --namespace=NAMESPACE
use profiles in NAMESPACE. This will result in confinement transitioning to using the new profile namespace.
-f FILE, --file=FILE
a file or directory containing profiles to load before confining the program.
-i, --immediate
transition to PROFILE before doing executing <command>. This subjects the running of <command> to the exec transition rules of the
current profile.
-v, --verbose
show commands being performed
-d, --debug
show commands and error codes
-- Signal the end of options and disables further option processing. Any arguments after the -- are treated as arguments of the command.
This is useful when passing arguments to the <command> being invoked by aa-exec.
